《WF in 24 Hours》读书笔记

1. 修改workflow1.xaml，添加Flowchart，添加Flowdesicion，添加CodeActivity2，并且名字改为下图所示：

2. CodeActivity1和2的代码如下：

    public sealed class CodeActivity1 : CodeActivity
    {
        // Define an activity input argument of type string
        public InArgument<string> Text { get; set; }

        // If your activity returns a value, derive from CodeActivity<TResult>
        // and return the value from the Execute method.
        protected override void Execute(CodeActivityContext context)
        {
            Console.WriteLine("executed in the left branch");
        }
}

    public sealed class CodeActivity2 : CodeActivity
    {
        // Define an activity input argument of type string
        public InArgument<string> Text { get; set; }

        // If your activity returns a value, derive from CodeActivity<TResult>
        // and return the value from the Execute method.
        protected override void Execute(CodeActivityContext context)
        {
            Console.WriteLine("executed in the right branch");
        }
    }

3. 修改program.cs

        static void Main(string[] args)
        {
            // Add the parameters via a dictionary object
            Dictionary<string, object> parameters = new Dictionary<string, object>();
            parameters.Add("Amount", 1200);

            Activity workflow1 = new Workflow1();
            WorkflowInvoker.Invoke(workflow1, parameters);

            // Pause the display
            Console.WriteLine("Press enter to continue.");
            Console.Read();
        }

4. 打开Workflow1.xaml文件，设置Flowdecision的condition为Amount < 1000

5. 还是在workflow1.xaml中添加Argument

6. 运行。结果如下：

7. 修改program.cs的Amount为900，运行。结果如下：
